Fase 6e: migrar Bullet al sistema de fisica vectorial

Browse Source 
Las balas pasan a ser cinematicas dentro del PhysicsWorld:
- body_.setMass(0.5), radius=0 (no colisionan fisicamente)
- disparar() setea body_.position + body_.velocity cartesiana (140 px/s)
- update() detecta salida del PLAYAREA via body_.position y desactiva
- postUpdate() sincroniza center_ desde body_.position
- desactivar() detiene el body para evitar deriva mientras inactiva

GameScene registra los bodies en init() y llama postUpdate(). El gameplay
sigue gestionando colisiones bullet-enemy/bullet-ship con check_collision
(el radio gameplay es BULLET_RADIUS=3, expuesto via getCollisionRadius).

Renames a camelBack (clang-tidy): get_owner_id->getOwnerId,
get_grace_timer->getGraceTimer.

MIGRATION_PLAN.md actualizado: Fase 6e cerrada, Fase 7 (SDL3 GPU) siguiente.
